Check the product facts AI shoppers are told
Proofsource product data accuracy shows which of your products AI answers describe correctly and which have a wrong price or attribute. For ecommerce and Shopify teams, it adds a store feed check against your live site and shopping reports on brands, merchants, products, keywords and trigger rate, so you can fix the data engines repeat.

AI product data accuracy, explained
AI product data accuracy is how closely AI answers match the real facts of your products: price, size, materials, compatibility, stock and the other attributes a shopper uses to decide. When someone asks an AI assistant which trail e-bike to buy, the answer often quotes a price or a spec. If that number comes from an old feed, a reseller listing or a stale page, the shopper gets the wrong picture before they ever reach your store.
Wrong product data usually has a plain cause: a feed that disagrees with the site, a page that hides key attributes behind scripts, or an old listing that engines still cite. Fixing it means finding which products are wrong, which field is wrong, and where the bad value lives.
Proofsource checks product attributes in AI answers against your data and lists the products and fields that are off. It checks your store feed against your site so the two tell the same story, and its shopping reports show which brands, merchants and products appear for your keywords and how often a question triggers product results.
How it works
Check whether AI answers get your product prices and attributes right, whether your store feed matches your site, and how products show up in AI shopping answers.
Read your catalog
Proofsource reads your products from your site and store feed.
Check the feed
The store feed check compares each feed item with what the product page shows.
Ask the engines
Shopping questions run on every engine your plan covers and the answers are captured.
Compare attributes
Prices and attributes in the answers are checked against your data, product by product.
Fix the source
Correct the feed or the page, then watch the attribute turn accurate in later answers.

Every capability, live today
3 shipped capabilities behind AI product data accuracy, each in the product now.
Product attribute accuracy
Checks the prices and attributes AI answers give for your products against your own data, and lists each wrong field by product.
Store feed check
Compares your store feed with your live site and lists the items where the two disagree.
Shopping reports
Reports on the brands, merchants, products and keywords in shopping answers, the trigger rate, a feed audit and captured answers.
Who it is for
Stop AI quoting an old price
Find the products where answers show an outdated price and fix the feed or page they come from.
Keep feed and site in sync
Run the feed check after catalog updates so engines and marketplaces read one set of facts.
See which products get shown
Use trigger rate and the products report to see which items appear for buying questions.
Why it matters
Right facts at the moment of choice
Shoppers see a price or spec in the answer before they visit, so it has to be right.
Field-level detail
You see the product and the field that is wrong, not a vague score.
One source of truth
The feed check keeps your feed and your pages telling the same story.
Proof the fix worked
Later answers show whether the corrected attribute reached the engines.

Questions about AI product data accuracy
What does AI product data accuracy mean?
It means the prices, sizes, specs and other attributes AI answers give for your products match your real data. Proofsource checks this product by product and names the field that is wrong.
Which AI engines does it check?
Proofsource tracks up to 10 AI engines: ChatGPT, Perplexity, Claude, Google AI Overviews, Google AI Mode, Gemini, Microsoft Copilot, Grok, DeepSeek and Meta AI. Which run depends on your plan.
Where do wrong product facts come from?
Usually from a store feed that disagrees with the site, an outdated page, or a reseller listing that engines cite. The store feed check catches the first one directly.
What does the store feed check do?
It compares each item in your store feed with what the matching product page shows, and lists the items where price, stock or attributes disagree.
What is trigger rate?
Trigger rate is how often a question produces product results in the answer. It tells you which buying questions are shopping moments for your category.
How is this different from Profound or Peec shopping tracking?
Profound and Peec track how often products appear in AI shopping answers, and do it well. Proofsource also checks whether the attributes in those answers are correct and whether your feed matches your site, so you can fix the data behind the answer.
How do I know a fix worked?
After you correct the feed or page, later answers are checked again and the product moves from wrong to accurate when engines pick up the change.
